Specification of Letters Patent.

Patented Feb. 4, 1919.

Application filed March 27, 1916. Serial No. 87,128.

To aZZ whom 2? may" concern:

Be it known that 1, Memo): J. HUooINs, a citizen of the United States, and resident of the city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Automobiles, of which the following is a specification.

This invention relates to automobiles, and particularly to the driving and speed controlling mechanism thereof, and its principal object is to provide simple, efficient, reliable. and improved means for driving the automobile at a great range of variable speeds, and for controlling its speeds with ease, convenience, and flexibility, and without causing any jar to the automobile or its occupants.

.Other objects and advantages will hereinafter appear.

T he accompanying drawing shows a general sectional plan view of the driving and speed controlling mechanism of the automobile, and a diagram of the circuits for operating the mechanism.

A drive-slrift 1 rotated by an oil engine 2 is split from a continuing shaft-section 1" thereof at 3 and extends to and passes through a casing 4 that contains suitable variable speed mechanism 4t. The shaftsection 1 is split from a continuing shaftsection 1 thereof at 5 and carries a gear 6 of said variable speed mechanismthat meshes with a gear 7 keyed upon a rotatable -.ountershaft,8. Said counter-shaft carries drive-gears 9, 10, and a cooperating gear 11 is splined upon -shaft-section 1 whcrewith diiferent speeds may be imparted to this shaft-section for driving the automobilewhcels, not shown. Thus, when the gear 11 is disposed in the neutral position showh, the gear (3 meshing with the gear 7 drives the counter-shaft 3 idly and no motion is imparted to the shaft-section. 1", and when the gear 11 is shifted to engage an internal coupling member 12 thereof with a couplingmember 13 forming partof the gear 6, the shaft-sections 1, 1. become coupled and the latter is driven at high speed directly from the former. Shifting of the gear 11 to mesh it with the r 9 drives the shaft-section 1 at lower or intermediate speed, and shifting the gear 11 to mesh it with an idler gear 14 that in turn meshes with drive gear 10 causes said shaftsection to rotate in an opposite direction for reversing the automobilewheels. To the drive shaft 1 is secured a generator field-element 15, and within said field is located a generator-armature 16 which is fixed to the shaft-section 1. At the exterior of the field 15, and concentrically with said drive shaft, is located a stationary generatonarmature 17 which is secured to the framework 18 of the automobile. A rotatable commutator 19 for the armature 16 is keyed to the shaft-section 1 and a commutator 20 for the armature 17 is secured to the frame-work 18. Frames'21 fixed to the field l5 carry brushes 22, 23 that are in contact with commutator l9, and brushes 2 1, 25 that are in contact with the commutator 20. A sleeve 26 forming part of the field 15 and surrounding the shaft-section 1 is provided at its extremity with a coupling-member 27, and a cooperatin coupling-member 28 splined upon said s aft-section may be shifted to engage with and disengage from the member 27, whereby the field 15 with its sleeve 26 may be locked to or unlocked from the shaft-section 1. The sleeve 26 carries contact rings 29, 30, 31, 32, 33, and 3 1, with which cooperate collector- brushes 35, 36, 37, 38, 39, and respectively that are secured upon a-bar 41 fixed to a bracket 42 extending from the casing 41.

Operating devices for the driving and speed controlling mechanism comprise suitable circuit controlling means consisting convonicntl y of a rotatable drum 43Ikeyed upon a shaft 44, which is journaled in the framework 18 of the automobile. The shaft 44 carries v a gear 45 .which meshes with a rack 46 ,tha is drawn by a rod 47 pivoted at 48 to a pedal 49. Said pedal is fulcrumed at 50 to the automobile frame-work and is normally swung toward the right, as viewed in the, drawing, by a spring 51, whereby pressing of said pedal contrary'to spring 51 rotates the drum 43, and releasing of the pedal causes said spring to lrestore it and rotate said drum baclnvardly to initial position.

Assuming that the entire mechanism is at rest and it is desired to start the automobile, the operator may depress a switch 52, or other suitable circuit controlling means, to join contacts 53, and then place his foot upon pedal 49 to therewith rotate the drum 43 partially and bring contact plates 54, 55, 5G, 57 in contact with terminal contacts 58, 59, (S0 and (31 respectively. .This con ducts current from battery 62 along wire 63, contacts 5 1. 58. wire 64, brush 10, ring 7 the brush 25 back to armature 17.

by energized and the field is rotated to drive the shaft 1 and start the engine 2. lVhen the engine is started running, the switch may be released and the circuit broken thereat, and the pedal 19 may be pressed farther forward to bring contact'plate 7 (3 in contact with. terminal contacts 58, 59,

and contact plates 77, 78 in contactwith terminal contacts (30, 61, whereupon the engine :2 rotates the field 15 to generate current in conjunction 'with the stationary arn'iature 17, which current is conducted from said armature along brush 21, wire 65, ring 31, brush -10, contacts 58, 7G, 59, wire 71, brush 39, ring 33, wire '72, fieldcoils 15, wire 73, ring 30, brush 36, wire 74, contact 60, any one of plates 77, across one of the variable resistances 79, along one of the connecting contacts 78, contact 61, wire 68, brush 35, ring 29, wire 67, and through The resistance 79 that first approaches the contacts 60, 61 is greater than its adjacent resistance, and the effect of contacting suc cessively with the plates 77, 78 and directing the current through these variable resistances successively is to cause a gradual building up of the current during its initial generation right after the engine has been started running. In order to start the automobile running the pedal 19 is pressed farther forward and the contact-plate 76 and contact-plates S0, 31, 32 are thereby caused to contactwith terminal contacts 53, 59, 83, 84, (30, 61 respectively, whereby the current is conducted from armature 17 along brush 24, wire 65, ring 34, brush 40, wire (3%, contact plate 76, contact 59, wire 71. brush 39, ring 33, wire 72, field 15, wire 73. ring 7 30, brush 36, wire 74, contact 30, plate 81,

contact 84, a wire 35, brush 37, ring 31. a wire 86. brush 23, commutator 19, a wire 87, armature 16, brush a wire 88, ring 32, brush 38, a wire 89, contact 83, plate 30,

a conduc ing wire 90, one oi variable resistances 91, any one of plates 82, contact 61, wire (38, brush 35, ring 29, wire (37, and through the brush :25 back to the armature 17. The generating elements 17, 15. 16 thus become connected in series and while so connected the rotation of the field causes gene ation of current in the stationary armature 17, energizing of the field 15,and generation of current in the rotatable armathe armature 16 along therewith electromagneticall and produces rotation thereof and of drive-sna't't section 1 which in turn transmits rotation to the automobile wheels. As the intensity of the electromagnetic flux between the elements 15, 16 increases, with theincrease of speed of field 15, the electric drag and torque between them increases, and consequently the slippage between these elements, or the speed of field 15 relatively to the speed of driven armature 16, decreases in a manner that tends to generate less current in the armature 16, and in order to avoid loss at torque between these elements, that would result from the said reduction of current generation, the current flowing n a h from aimatuie 14 is fed through the armature 16, in the seriesing ofthe three ele-' ments, and operates to intensify the electromagnetic flux andv to thereby maintain or increase the electric drag and torque between the elements 15, 16. The resistances '91 decrease in the order in which they approach the contacts 60, 61, and therefore the effect of contacting of the various plates 82 with said contacts, by operation of pedal 19, and directing the current to flow through these Variable resistances and through the seriesed three generator elements 17, 15, 16 is to increase and decrease the current generation, to regulate the intensity of theclec- 10'0 tromagnetic drag and torque between the elements 15, 16, and to drive the armature 10 at variable speed to impart various speeds to the automobile. To secure further regulation of torque or intensity of electron'iagnetic drag between the elements 15, 16. the pedal 9 may be pressed farther to bring plate 76 and contact- plates 92, 93, 91, 95 in contact with the terminal-contacts 58, 59, as, 8-1, 60, c1. conducted from armature 17 along brush 2%, wire (35, ring 3%, brush 40, wire (51. 'contact 53. plate 76, contact 59, wire 71, brush 39, ring 33, wire 72, field 15, wire 73, rin 30, brush 36. wire 71, I I b of plates 94, any one of variable resistances 96., any one of plates 5, contact 61. wire 68, brush 35, ring wire {37, and brush 25 back to the armature 17; and the current generated in armaturelfiis conducted in a 120 short circuit from brush 22 along wire 88, ring 32, brush 38, wire 89, contact 83, anv one of plates 92, any one of variable resistances 97, any one of plates 93, contact 81,

wire 85, brush 37, ring 31, wire 86, and 125 17 and the current in the driven armature 136 The current is thereby contact 60, any one 16 flowing in short circuit is generated by coaction of this armature with said iield. Said short-circuiting of the armature 1b, and the coincident regulation of the generation and the flow of current through the generator elements is productive of additional large ange of variation of speed ot the driven ari :ature 10 and the drive-shaft section 1. lVhen the armature 16 has acquired its full speed, which is nearly like that of the field 15, the coupling member 28 may be shifted toward the left, as viewed in the drawing, and caused to engage the sleeve 26, whereupon the generator-elements 15, 16, as well as the shaft-sections 1, 1 become mechanically coupled and the driveshaft section 1 is driven directly from the engine 9'. The pedal 40 may be then released, the circuits broken, and the automobile continued to be driven directly from the engine until it is again desired to drive .it at variable speeds through electrical 5exible control, when the coupling members 27, 28 may be disengaged and the pedal 49 again manipulated to drive the automobile through the operation of the generator elements 17,

It will be evident that whether the driveshaft section 1 is driven directly from the engine 2, by coupling of the members 27, 28, or through the medium of the electric generator, its continuing shaft section. 1 that drives the automobile wheels may be driven either directly therefrom, by coupling the members 12, 13, or it may be driven through the gears of the variable speed mechanism 4 In this manner ready and convenient changing of speed may be performed whether driving't'rom the engine or through the operationor" the generator, whereby greater range or" speed variation may be thus further secured to meet various changing road conditions or various driving exigencies.

\Vhile the automobile is being driven directly from the engine 2, by the mechanical .couplingof the generator-elements 15, 10,

and the shaft sections 1, 1, current may be generated by the coaction of the relatively driven elements 17,15 to charge battery: (32, In order to charge said battery :1 switch 98 is closed-and the pedal 49 is pressed to bring contactplates 09, 100, 101 and 102 in contact with terminal contacts 58, 50, (30, (31 respectively, whereby current is conducted from armature 17, along brush '24, wire 65,

ring 34, brush 40, wire 04, contact 58, plate 99, resistance 103, plate 100, contact 50. wire 71, brush 30, ring wire 7'2. field 15, wire 73, ring 30, brush 36, wire 74, contact 60, plate 101, resistance 104, plate 102, contact 61, wire 68, ring- 20, brush 35, wire 67. and through the brush 25 back to the armature .17, and current is conducted to charge the battery along a branch circuit leading from 105, wire 69, through along a wire 106 to ill be evident that all of the above described operations of the driving and speed controlling mechanism can be performed readily, rapidly and conveniently by the mere operation of the toot-pedal l9.
